Be it known that I, OLIVER I-l. STUCK- wIscn, a citizen of the United States, residing at Indianapolis, in the county of Marion and State of Indiana, have invented new and useful Improvements in AutomobileHeaters,. of which the following is a full, clear, concise, and exact description, reference being had to the accompanying drawing, forming a part of this specification.

My invention relates to automobile heaters.

Among the objects of my invention is to provide an improved automobile heater in which the heat can be easily anddefinitely regulated, and which will utilize a large portion of the heat in the exhaust gases which pass through the heater.

Further objects will appear from the detailed description to 'follow taken in con: nectionwith the appended claims.

In the drawings in which I have shown two embodiments of my invention- Figure 1 is a side elevation of an automobile, parts being broken away-to show the location and arrangement of the heater;

Fig. 2 is a section on the line 2-2 of Fig. 3;

Fig. 3 is'a plan view of the heater, parts being broken away to show the interior construction;

- Fig. 4 is a section on the line 4-4. of

Fig. 3;

' Fig. 5 is a section on the line of Fig.2;and r V Fi 6-is a section-on the line 6-6 of Fig. 2.

I have shown my invention in connection with an automobile 8 having an internal combustion engine 9 providedwith an exhaust manifold 10 leading to theexhaust pipe 11. The floor 12 of5th'e automobile is provided with an opening 13 in which is lo-' cated the heater. This heater. comprises a casin or container 14. which fits in the ppenmg 13 and contains a radiator 15 which 11 through an upwardly and rearwardly- 1nclined inlet conduit '16 and an outlet .con-' duit 17 which extends rearwardly in the game horizontal plane of the radiator. Communication between the exhaust pipe 11 and the inlet-conduit 16 is controlled by means of a forwardly projecting flap valve 18 to" regulate the quantity of gas flowing through Specification of Letters Patent.

the radiator. The casing 14 is provided with a cover 19 having a plurality of openings 20 therein for the escape of the heated air.

tal plane throughout the radiator as shown in,Fig 3. In this passage are located a plurality of bafile pins or plates 24 against which the hot gases impinge causing these plates to become heated and thus utilize a, large portion of the heat in the gases. Nipples 25 and 26 lead to and from the U-shaped passage and are in communication with the conduits 16 and 17, respectively. The-conduits 16 and 17 are connected with the exi'espectively.

The fitting 27 comprises a saddle portlon the side of the exhaust plpe, a

of the exhaust pipe, bolts 30 connecting the saddle and yoke portions, and a curved tubular portion 31 m communication with the conduit '17 and with the opening 32 in the side'of the exhaust pipe. V.

The fitting 28 comprises a sem -cylindrlcal portion 33 fitting the upper'slde of the exhaust pipe and provided with a flat upper side, a semi cylindrical portion 34 fitting the lower side of the exhaust pipe, bolts 35 connecting the cap portion 36 fitting on top of the portion 33 and provided with a nipple 37 in .communication with the conduit 16. The 'portions 33 and 36*are provided with registering half bearings in which is rotatably mounted a rock shaft 38 to which the flap valve 18 is secured. The upper side'of the and the semi-cylindrical porare rovided with registering "open. ings,39 and 40 through which the exhaust pipe is in communication with the conduit 16; the openings 39 and 40 being ust large enough to permit the valve 18'to operate and The valve'18 is operated b mean oia haust pipe 11 by means of fittings 28 and 27 portions 33 and 34 and a flat lid to cause a vacuum at the e haust pipe of the to deflect a portion 11, the'dow'ot the deflected gases will'he in dtl ' tor where they v passage of thesgases through the running the exhaust gases escape-through the-manifold .10 and exhaust pipe 11. By

adjusting the valve 18 by means of the lever 43 a portion of the exhaust gases can be de flected through. the conduit 16 to the radiawill strike against the hams plates 24 and heat the radiator causing the air within the casing 14: to become heated and-causing the heated air to escape upwardly through the openings 20 placed ycooler air through the openings 22. The valve 18 can he setto deflect any desired proportion of the exhaust gases through the radiator.'-

n will be observed ram inspection of rig,

2 of the drawing that the gases are exhausted from the radiator in app ximatelythe horizontal plane of the radiator, andthe intake from exhaust pipe 11 is considerahl below the horizontal plane of the radiator; consequently,-when the valve 18 is operated to deflect a poitionotthe ases from the exhaust pipe 11 into the e, the portions of the gases not deflected will be forced along the exhaust pipe 11, and, owingto the short vertical connection at the exhaust end of the radiator, the passing gases will tend xhaust end of the radiator which willpull the deflected gases rapidly through the radiator, thereby securing'a maximum of 'heat units and at the same time appreciable resistance to the engine exhaust. In other words, this construction, provides ap' arrangement ot parts. to create a greatersuction at the exhaust end of the radiator thanat the intake end, and

this is accomplished by connecting the ex-" radiator to exhaust pipe 111 near to thehorizontal plane of. the radiator and connecting the intake pipe to exhaust pipe 11 considerably below the plane of the radiator.. To further facilitate the rapid intake'pipe 16' and its connections are inclined rearwardl from pipe ll to the radiaton so that W cm, the valve 18 is' adjusted of the gases from pipe the general direction ofthe main exhaust,

other important-feature of the invention is'the relatively long flap valvel8 which is hinged or pivoted can be conveniently operated V of the area of to be reinto said inlet meeting the radiator,

naeaaea I at its upper end to the upper and rear side ot'the pipe 11 and intake 16. thus formed and when it is positioned to deflect a portion of the gases to the radiator, it efi'ectually closes a portion the pipe 11 and forms an inclined bottom in continuation of the intake passage. 'When this valve closes the intake passage, it lies at the top of the pipe 11 and does not restrict the normal area of said pipe.

Having I claim as new and desire to secure by Letters Patent is 1. The combination with an exhaust pipe of an automobile, of a radiator having a continuous horizontal passage therethrough, an inlet conduit connecting one side or the radiator to said exhaust pipe and inclining y Y the connection oil-the inlet conduit with the exhaust" pipe, and means for deflecting a portion of the conduit.

an inlet conduit connecting v one side of the radiator to said eaust pipe and inclining upwardly and rearwardly from said exhaust pipe to said radiator, an outlet conduit coin said exhaust pipe and extending rearwardly from said radiator to said exhaust connection of said outlet conduit with said exhaust pipe being substantially in the hubri-v iator and nearer to nto. said'inlet conduit, said means being adapted to project forwardly insaid exhaust pipe and tor-m aninclined bottom in con tinuation of the inclined In witness whereof, T
